The European Space Agency (ESA) developed the CryoSat mission to determine variations in the thickness of the Earth's continental ice sheets and marice ice cover. CryoSat will also provide high-resolution radar altimeter measurements over the margins of the Antarctic and Greenland ice sheets to test the prediction that Arctic ice is thinning due to global warming and to determine to which extent the Greenland and Antarctic ice sheets are contribution to global sea level rise.
The mission will also continue the time-series of Antarctic and Greenland elevation change provided by the ESA's Earth Remote Sensing (ERS) and ENVISAT satellite altimeters.
